Eaton CS8264 – Frequently Asked Questions

1) What wire sizes can I land in the Eaton 50A armored locking connector?
The Eaton armored locking connector takes #10 through #6 AWG conductors, including the grounding conductor, and terminates with back wiring. For a 50A load you're realistically pulling #6 AWG copper, which is at the top end of the range, so the terminals will accept it without a reducing splice.
2) Will this Eaton connector mate with a standard NEMA locking receptacle like an L6-50?
No. This Eaton device is a non-NEMA configuration, so it will not blade-match a standard NEMA locking pattern. It's ordered in two pole/wire configurations, 2-pole 3-wire (CS8264) and 3-pole 4-wire (7764). If your opposite half is a NEMA pattern, use a NEMA device instead, such as the Pass & Seymour Turnlok L6-15 connector or a Leviton industrial locking connector in the matching configuration.
3) What cord diameter will fit the clamp on this 50A Eaton locking connector?
The cord grip takes jackets from 0.68 to 1.13 inches (17.3 to 28.6 mm) in diameter. Check your SO or SOOW cord OD against that before you cut it in; a heavy 6/4 cord can run past the top of that range.
4) Do I order the 2-pole 3-wire CS8264 or the 3-pole 4-wire 7764?
Match it to the circuit. CS8264 is the 2-pole 3-wire version, for a single-phase 250V load with an equipment ground. 7764 is 3-pole 4-wire, for three-phase or a circuit needing a third hot plus ground. Both carry the same 50A, 250V rating and the same armored stainless construction.
5) Can I use this 50A connector on a 480V circuit?
No. The Eaton armored locking connector is rated 250V maximum, so it's limited to 120/240 or 250V single- and three-phase circuits. A 480V feed needs a device rated for it.
6) I need a locking connector for a 30A 125V circuit instead of a 50A one - what should I use?
The Eaton armored locking connector is rated 50A at 250V, so it is not the right device for a 125V 30A cord set. For that circuit, the Leviton 2313 is a 3-wire 2-pole industrial grade locking connector rated 125V 30A in the NEMA L5-30R configuration. Note that the Eaton device is non-NEMA, while the Leviton 2313 carries a standard NEMA pattern, so the two will not mate with each other's plugs.
7) Is there a lighter-duty locking connector for a 250V circuit that does not need 50 amps?
Yes. The Pass & Seymour Turnlok PSL615-C is a NEMA L6-15 locking connector rated 15A at 250V with a nylon body, which covers the same 250V range at a much lower current. The Eaton armored connector is an extra heavy duty 50A 250V device with a stainless steel body and glass filled nylon face, and it is non-NEMA, so it will not mate with an L6-15 plug.
8) What do I use for a 4-pole 5-wire locking connector? Does Eaton cover that?
The Eaton armored locking connector is built in 2-pole 3-wire and 3-pole 4-wire versions only. For a 4-pole 5-wire device, the Leviton 2323 is an industrial grade locking connector in a 5-wire 4-pole configuration rated 20A, which is a different current class from the Eaton's 50A rating.
9) Can this locking connector be used outdoors or in a cold warehouse?
Operating range runs -40 to 90 C (-40 to 194 F), so freezer rooms and unheated yards are within spec. The body is stainless steel with a glass filled nylon face, which handles impact and corrosion in industrial settings. It is a connector body, not an enclosure, so any wet-location protection still comes from the cord cap arrangement and how you rig it.
10) How much room do I need to land this Eaton armored connector in a panel or on a cord?
Overall it measures 5.73 x 3.1 x 2.68 inches, with the 5.73 inch figure the length/depth. Allow that plus a bend radius for #6 conductors behind it, since it is a back-wired device and the conductors enter from the rear.
11) Is this connector rated tough enough for portable power on a jobsite or heavy machinery?
It's an extra heavy duty grade device, one step above the industrial grade connectors most shops stock, with zinc plated brass contacts and an armored stainless shell. That's the build you want for portable cord sets that get dragged and dropped. Lighter-duty industrial grade options in the same family of products include the Leviton 2413 3-pole 4-wire 125/250V connector.
12) We are running connectors in a washdown and outdoor yard area - how does the Eaton compare to a non-metallic connector?
The Eaton is an armored connector with a stainless steel body and a glass filled nylon face, rated for -40 to 90 C service, and it uses zinc plated brass contacts. The Bryant 71020NC from the 7 Series is a non-metallic NEMA locking connector, so it has no exposed metal shell at all. The choice comes down to whether you want the impact protection of the armored metal shell or an all non-metallic housing, and whether your plug is a standard NEMA pattern, since the Eaton is non-NEMA.
13) My machine feed is 3-phase 125/250V - does the Eaton 50A connector work, or do I need something else?
The Eaton armored connector is offered as a 2-pole 3-wire and a 3-pole 4-wire device at 250V. If your drawing calls specifically for a 125/250V 4-wire 3-pole device, the Leviton 2413 is an industrial grade locking connector in that exact 4-wire 3-pole 125/250V configuration. Confirm the pole and wire count on the mating plug before ordering either one.
14) Can I substitute a Bryant 70520NCC for the Eaton 50A armored connector?
They are not interchangeable as a matter of course. The Bryant 70520NCC is a 705 Series locking connector, while the Eaton is a non-NEMA armored device rated 50A 250V accepting #10-6 AWG with back wiring. Match the pole and wire count and the mating plug configuration on your existing cord before treating one as a drop-in for the other.
15) Our spec sheet says industrial grade locking connector - is the Eaton above or below that?
The Eaton armored connector is classed extra heavy duty, which sits above a standard industrial device, and it is CSA certified. The Leviton 2423 and 2413 are both industrial grade locking connectors. If the spec is written as a minimum of industrial grade, the Eaton meets it; if the spec names a particular NEMA pattern, check that first, since the Eaton is a non-NEMA configuration.
